Application filed February 9, 1912. Serial No. 216,2 5.

To all whom it may concern, I

Be it known that I, It never C. SFHAPER, a citizen of the United iltit s residing at Louis, lilissouri have in exited a certain new and useful Improvement in Scale-Been:

Locks and Switch Operating Devices, of which the following is a full, clear, and exact description, such as skilled in the art to which it/appertains to make and use the some, reference being had to the accompanying drawings, forming part of this specification.

"My invention relates to a device for lockins; the beam or lever of 21 scale or weighing machine and for operating the switch of an electric lamp which letter is utili ed in a weight indicator for the scale or for illuminating the graduated face of the scale beam or lever.

The invention herein disclosed is particularly designed for use in connection with the weightindicetor for scales disclosed in.

my copending al'aplication filed December 18, 1917, Serial Number 207,683. 4

The apparatus disclosed in my copending application includes mechanism connected to and actuated by the grzrduetecl beam or lever of a scale tor automatically indicating on n screen or ground glass the amounts of the loads placed on the scale platform and this indicating mechanism includes an electric lamp the light from which is needed only while the indicating mechanism is in service.

Further, it is desirable that the scale beam to which the indicating mechunism is connected be locked against vibratory movement while not in use, and it is the object of my invention to provide simple and eliicient means for lockingthe scale beam against moveznent and at the same time manipulat- QDQChglilgIii "hfill burn. In

mg :1 switch in the circuit lending to the lump iuthe indicating means, thereby cutting said lamp out of service simultaneously with the beam locking operation. Necessarily, a reverse movement imparted to the device contemplated by my invention will release the scale beam or lever so that the s me can operate in the usual manner and at m time close the switch in the electric circuit so that the lamp in the indicating some igistunces, it

will enable others table of an ordinary beam jeessery to place an electric lamp in a UItIiOD Where its will fall directly on the graduated face of the scale beam or lever in order to effect a ready reading of the weights placed on the scale platform and indicated on said beam or lever, audit is one of the objects of my invention to provide it device'which can be utilized for simultaneously manipulating the switch controlling the circuit to this lamp and looking or unlocking the scale beam with which said lamp is associated.

W'ith the foregoing and other objects in View, my invention consists in certain. novel features of construction and arrangement of parts, hereinafter more fully described and claimed and illustrated in the eceompanying drawings, in whieh-- Figure l is a front elevations]! View of the upper portion of a beam seuleethe same be- 111gv equipped with an automatic indicating mechanism and with a, scale beam lock and switch operating device constructed ,inaccordance with my invention.

Referring by numerals to the accompany 0 ing drawings and particularly Figs. 1 to 4 inclusive, which illustrate a prhctical em bodiment of my invention, 10 designates the scale, 11 the graduated beam or lever thereof, and 12 the housing which incloses the operating mechanism of the automatic Weight indicator. Secured in any suitable manner on top of the housing 12 is a post 13 and mounted for vertical adjustment thereupon is a plate 14 100 the, upper end of which is provided with a, collar or housing 15 which serves as a seat for an ordinary electric switch 16 This In series with one. of, the
